Marine macroalgal communities were examined near the outflow of acid mine drainage (AMD) from the Britannia Mine, British Columbia, Canada. No marine algae were present within 100 m of the mouth of Britannia Creek, which carries the AMD into the marine environment. At greater distances (300-700 m) from this Creek, mean summer cover of filamentous green algae, mostly Enteromorpha intestinalis, was >60%, which was significantly higher than at nearby reference stations. At still greater distances (600-1000 m) from Britannia Creek, Fucus gardneri dominated algal communities that were similar to those at reference stations. No consistent differences were detected in mean plant length, mean per cent cover or mean oocyte production between F. gardneri near Britannia Creek and those at reference stations. Cu body burden in F. gardneri near Britannia Creek was five to 17 times higher than in reference plants.
在加拿大不列颠哥伦比亚省大不列颠矿酸性矿山排水（AMD）流出附近，对海洋大型藻类群落进行了调查。携带AMD进入海洋环境的大不列颠溪河口100米范围内没有海洋藻类。在距该溪流更远的距离（300 - 700米）处，丝状绿藻（主要是肠浒苔）的夏季平均覆盖率>60%，这显著高于附近的参考站点。在距大不列颠溪更远的距离（600 - 1000米）处，加氏墨角藻主导着藻类群落，这些群落与参考站点的群落相似。在大不列颠溪附近的加氏墨角藻与参考站点的加氏墨角藻之间，未检测到平均植株长度、平均覆盖率或平均卵母细胞产量的一致差异。大不列颠溪附近的加氏墨角藻体内的铜含量比参考植株高5至17倍。
